The sideways heart is the heart motif turned on its side - a tilt that changes the reading of the shape from sentimental to stylish, the unexpected orientation signaling that this is a design choice rather than a default. Rachel Zoe pairs it with a CZ halo surround in 14K gold over sterling silver, the diamond-cut finish on the heart center adding texture while the CZ halo provides directed sparkle at the perimeter. Butterfly back closure. A heart earring that earns its fashion credentials through the specificity of its execution.
